Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77766, here are decompositions:

5 + 77761 = 77766
19 + 77747 = 77766
23 + 77743 = 77766
43 + 77723 = 77766
47 + 77719 = 77766
53 + 77713 = 77766
67 + 77699 = 77766
79 + 77687 = 77766

Showing the first eight; more decompositions exist.
